As the grain size of a metal increases, its ductility ______
As the grain size of a meal increases, its ductility ______
Right Answer is:
Decreases
SOLUTION
As the grain size of a meal increases, its ductility decrease.
Lower the grain size, more is the number of grain boundaries, thus more is the yield strength, thus more is the ductility. So, as grain size increases, its ductility decreases.
